Abstract: Liquid is cooled in a columnar vessel 2 having an inlet 4 and an outlet 6 for the liquid. The cooling is effected by introducing liquid cryogen into the vessel 2 through a pipe 14. The liquid cryogen vaporises and crates turbulence in the liquid in the vessel 2. Perforated plates 12 dampen the turbulence and disengage the vaporised cryogen from the liquid being cooled. Pressurised gas is introduced from an inlet 16 into the liquid beneath the liquid cryogen. This pressurised gas crates turbulence in the region where the cryogen enters the liquid and thus is able to prevent local freezing of the liquid in the mouth of the pipe 14. The liquid is typically water and the liquid cryogen typically liquid nitrogen.

Abstract: The invention relates to a method of pattern recognition comprising a first learning stage in the course of which a sum of data extracted from known patterns is memorised and a recognition threshold is defined and a second stage consisting in comparing with this threshold the data extracted from the pattern to be recognised. This method is characterised in that the extracted data of known patterns and those extracted from the pattern to be recognised are transformed into normed vectors and in that to the normed vector arising from the pattern to be recognised is applied a summing formula introducing all the vectors arising from examples of the same pattern and which permits recognition of the unknown pattern if the value obtained is greater than or equal to the value of the recognition threshold defined during learning.
